【Example】

Next, the present invention will be explained in detail based on the embodiments shown in the drawings. 1 and 2 is an auxiliary stop lamp according to the present invention. The auxiliary stop lamp 1 is installed closely to the rear window 10. The points are the same as those of the conventional example, but with this invention, it is possible to attach it to the rear window 10. A lens 2 that is attached more directly, a housing 3 that is attached to the lens 2, and a front a substrate 4 supported by being screwed onto the housing 3; A plurality of LED light emitting elements 5 are arranged as light sources.

[0006] The lens 2 is, for example, formed of a transparent member into a substantially rectangular parallelepiped shape, Furthermore, as shown in FIG. The inclination angle α of the vertical side of the rear window 10 is corrected on the surface that is on the back side with respect to the direction. Lens cut 2a such as linear Fresnel cut is applied. There is. In forming the lens 2, the horizontal curvature of the rear window 10 is It is preferable to use a highly flexible resin member in order to conform to the curvature of the curve. If the shape is curved along the curvature mentioned above, it will be less flexible, such as glass. It is also possible to form it from a member.

[0007] The housing 3 is formed of an opaque resin member or the like in a substantially box shape. For example, a suitable method such as a protrusion 3a that fits into the recess 2b formed in the lens 2 is used. At this stage, the lens 2 can be engaged with the rear window 10, and when it is engaged, the rear window 10, In other words, it is curved along the curvature of the lens 2, and the inner surface has, for example, the outer diameter side of the side surface. This will be explained later by screwing onto the stepped portion 3b provided by an appropriate means such as tightening the The substrate 4 is supported. Further, the housing 3 has a box-like depth that accommodates the board and the depth of the box. It is supposed to cover up to the sides of the lenses 2.

[0008] The board 4 is made of a flexible member called a flexible printed circuit board, for example. A plurality of LED light emitting elements 5 are provided on the surface of the substrate 4 facing the lens 2. are arranged in a row, for example, corresponding to the lens cuts 2a, and at the same time On this board 4 are resistors ( (not shown) are also mounted on the housing 3. When attached to the lens 2, it follows the curvature of the rear window 10. It is said to be highly curved.

[0009] Next, the operation and effects of the auxiliary stop lamp 1 of the present invention having the above structure will be explained. To explain this, the lens cut 2a corrects the inclination angle α of the rear window 10. The lens 2 can be directly attached to the rear window 10 by applying This eliminates the need for a surrounding wall that protrudes forward in the irradiation direction of the lens 2, which was essential, and reduces the amount of protrusion into the vehicle interior. It is possible to reduce the In addition, by directly bonding the lens 2 and the rear window 10, the LE Light from the D light emitting element 5, that is, the light source passes through the rear window 10 and reaches the viewer. The number of interfaces with the air along the path to the front has been halved from the conventional four to two.

0010 FIG. 3 shows another embodiment of the present invention, in which the previous embodiment is different from the housing 3. In contrast to the case where the board 4 was previously attached by screwing it to the board 4, in this embodiment The lens 2 is provided with a side wall 2c, and the rear end of the side wall 2c and the housing 3 are connected to each other. The substrate 4 is sandwiched between the stepped portion 3b, and by doing so, By omitting the step of attaching the board 4, it is possible to further reduce the number of assembly steps. Also, above The functions and effects other than those described are the same as those in the previous embodiment, so detailed explanations are omitted here. Omitted.

[0011] Incidentally, the LED light emitting element 5 is made of, for example, a so-called dome-shaped resin mold. However, it is also possible to directly mount the LED chip on the board 4 and use it. If it is used, it will be possible to make it even thinner, and even more favorable effects will be obtained. Become. Further, the lens cut 2a is not limited to a Fresnel cut, and for example, For example, it may be a combination of a cylindrical lens and a prism (see Figure 3). Any structure may be used as long as the inclination angle α of the rear window 10 can be compensated for. It is.

[Effect of the idea]

As explained above, with this invention, this rear window is attached to the rear window. A lens with a lens cut that corrects the tilt angle of the lens is directly glued, and multiple A flexible substrate on which an LED light emitting element is arranged is covered with the flexible substrate and attached to the lens. The auxiliary stop lamp is configured to be sandwiched between the housing and the lens. Conventionally, in order to correct the inclination angle of the rear window, a lens is placed in front of the lens in the irradiation direction. The depth of the auxiliary stop lamp has been shortened by eliminating the need for the surrounding wall that was previously provided for the purpose. By reducing the amount of protrusion into the vehicle interior, it reduces the discomfort felt by passengers, and at the same time reduces the visibility of the driver. It also reduces interference and has an excellent effect on improving practicality.

[0013] In addition, by attaching the lens directly to the rear window, this The interface with the air that exists in the optical path of the auxiliary stop lamp is reduced by half, and the It reduces the amount of light lost, making the lamp brighter, and has an excellent effect on improving performance. becomes.
